TUBING COMPANY, OF CHICAGO, ILLINOIS, A CORFORATION 0F ILLINO t a i tra fr: s E ai. EN( s a t is c awa than l CAR-VESTIBULE DIAPHRAGM.

Application led September 19, 1924.

To all whom t may concern.'

Be it known that I, HARRY H. Sor-morsa, a citizen of the United States, and a resident of the city of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in a Car-Vestibule Diaphragm; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, and to the numerals of reference marked thereon, which form a part of this speciiication.

This invention relates to car vestibule diaphragme designed more particularly for connecting Pullman cars and the like.

Diaphragme as ordinarily constructed are formed to expand and contract on the bellows principle and the fabric at the lines of fold becomes worn and breaks as the result of the continual flexing back and forth.

Further, sparks from the engine fall upon the top of the diaphragm and burn holes` therein. Y

One of the principal objects of the present invention is to provide a diaphragm in which flexing of any fabric portions is reduced to a minimum.

A. further object is to provide a dia phragm which is not liable to be burnt by sparks or cinders from the locomotive.

Other and further important objects of this invention will be apparent from the disclosure in the accompanying specification and drawings.

The invention (in preferred form) is illustrated in the drawings and hereinafter more fully described.

0n the drawings 2- Figure l is a transverse vertical section of a car vestibule diaphragm constructed in accordance with the present invention.

Figure 2 is ahvertical section through the` diaphragm.

Figure 3 is a section on the line 3 3 of Figure 2.

Figure 4 is a section on the line t-hlof Figure 2.

Figure 5 is a plan view of one part ofthe diaphragm partly in section.

igure 6 is a view similar to Figure 5 with parts removed.

Figure 7 is a section on the line 7-7 of Figure 2.

As shown on the drawings:

The face plate 10 is connected to the car Serial No. 738,580.

end by the usual buffer-rods 11 passing through apertures in the end plate 12 and provided with the customary coiled springs not shown.

The diaphragm proper consists of a horizontal top plate 13 of metal and legs i) preferably of fabric. The plate 13 is ar` ranged to telescope into a recess 14 in the car end while the legs simultaneously telescope into recesses 15. The side edges 16 of the plate 13 are cut obliquely as shown in Figure 5 to allow the face plate to move angularly with respect to the car end. At one end the plate 13 is formed with an upstanding flange 17 which loosely tits within the pocket formed between the face plate 10 and a plate 18 riveted thereto. This loose connection allows relative movement of the plates 10 and 13 in a vertical plane.

For attaching the legs 9 to the face plate, angle bars 19 are attached to the latter. The legs may be secured to these bars in any convenient manner such as lacing, bolts or rivets.

At their upper ends the legs are bent over for slidable engagement with pockets formed on the underside of the plate 13 by riveting plates 20 thereto. This sliding connection allows angular movement to take place between the top and the legs. The corner of the legs are cut away, as at 29, to allow of this movement.

The recess 15 into which the legs slide is formed by bending a sheet of metal 21 into -shape form and securing one edge to the side framing 22 of the. car. For additional strength the metal U may also be attached to the I-beam 23 by an angle bar 24.

The recess lt is formed by the plates 2r and 26. In order to keep dirt from entering the recess 14 a strip of fabric 27 is clamped to the end plate by a strip 28.

I am aware that numerous details of construction may be varied through a wide range without departing from the principles of this invention, and I therefore. do not purpose limiting the patent granted otherwise than necessitated by the prior art.

I claim as my invention:

1. A car vestibule diaphragm comprising a horizontal metal top and two fabric legs and a recessed member adapted to receive telescopically said top and legs.

2. A car vestibule diaphragm comprising a horizontal metal top formed with laterally open pockets, two fabric legs having their ASSIGNOR TO MOI-TON IVANITFAC lli) upper ends slidably engaged in said pockets, and a recessed member adapted to receive telescopically said top and legs.

3. A car vestibule diaphragm comprising two legs, a horizontal metal top with obliquely cut sides to allow angular movement between the two cars, laterally open pockets in said top slidably to receive the upper ends of said legs and thereby allow relative angular movement between the legs and top.

4L. A car vestibule diaphragm comprising two fabric legs, a horizontal metal top with obliquely out sides to allow angular movement between the two cars, laterally open pockets in said top slidably to receive the upper ends of said legs and thereby allow relative angular movement between the legs and top, and a recessed member adapted telescopically to receive said legs and top.

In testimony whereof have hereunto subscribed my name.
